IMPROVEMENT IN DEVICES FOR DETACHING HORSES.

Specification forming part ofLetters Patent No. 147,961, dated February 24, 1874; application filed September 20, 1873.

To all whom it may concern:

Be' it known that I, Ronr. NEsBrTT, of Blairsville, in the county of Indiana and State of Pennsylvania, have invented a new and valuable Improvement in Releasing Whittletrees; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings inaking a part of this specification, and to the letters and iigures of reference marked thereon.

Figure l of the drawings is a representation ot' a part sectioivof my releasing device for whit'etrees. Fig. 2 is a front view of same.

lhe object of this invention is to improve releasing devices for whiftletrees, as will be hereinafter described.

In the accompanying drawing, A represents the wooden portion of the whiietree, which is recessed and longitudinally perforated for receiving the releasing device. B B represent two metallic sheaths or ferrulcs, which are tted upon the ends of the wooden portion A, and have loops or eyes a a formed on their outer extremities. G C represent two bolts, which play longitudinallyP inthe whiffletrees, and extend through the ends of the sheaths, so as to abut against the outer ends of the loops a a, and hold therein the ends of the traces. These bolts are acted on by helical springs c, which bear against cross-plates I), and operate to force the bolts outwardly against the loops a. The inner ends of these bolts are pivoted at e to curved levers D, which latter are pivoted at f to wearing-plates seated into the recesses in the whiftletree, as shown in Fig. 1. The levers D pass out through slots and are curved around, so that, when the bolts C are in their norma-l position, (shown in Figs. l and 2,) the outer ends of these levers abut vagainst the side. of the whifetree, and are there held by the springs c. These levers D are curved, for the purpose of having them out ofthe way, except when the bolts are retracted, and at the same time allowing them to be made of a proper length to ai'ord a good purchase in retracting the bolts, which is done by means of cords or chains carried up to a convenient position for the driver. It is importa-nt that the bolts-G should be locked when they are retracted to free the traces, and for this purpose the sheaths B are eut away so as to leave shoulders or catches at i 2'., behind which the levers are forced uby means of inclined springs S S. These springs act toraise the free ends of the levers D; consequently the pivotal attachments of these levers should be suiciently loose to allow the levers to rise as they are drawn back.

Spring releasing-bolts for releasing traces fromwhifiietrees are not broadly herein claimed by nie.`

Vhat I claim as new, and desire to secure by Letters Patent, is

The combination of rod C, actuating-lever D, springs c and S, and sheaths B, having shoulders i, applied to a Whiftletree, as and for the purposes specified.

ln testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
